Objective: We conducted a prospective randomized controlled trial in postliver transplant patients to evaluate intensive inpatient glycemic control and effects on outcomes to 1 year. Research Design and Intervention: A total of 164 patients [blood glucose (BG) >180 mg/dL] were randomized into 2 target groups: 82 with a BG of 140 mg/dL and 82 with a BG of 180 mg/dL. Continuous insulin infusions were initiated and then converted to subcutaneous basal bolus insulin therapy by our glucose management service. Results: The inpatient mean BG level was significantly different (140 group, 151.4 ± 19.5 mg/dL vs 180 group, 172.6 ± 27.9 mg/dL; P < 0.001). Any infection within 1 year occurred in 35 of the 82 patients (42.7%) in the 140 group and 54 of 82 (65.9%) in the 180 group (P = 0.0046). In a time-to-first infection analysis, being in the 140 group resulted in a hazard ratio of 0.54 (95% confidence interval, 0.35 to 0.83; P = 0.004); the difference between the 2 groups was statistically significant at 1 month (P = 0.008). The number with adjudicated transplant rejection was similar between the 2 groups [17 of 82 (20.7%) and 20 of 82 (24.3%) in the 140 and 180 groups, respectively; P = not significant]. Severe hypoglycemia (BG ⩽40 mg/dL) occurred in 3 patients (2 in the 140 group and 1 in the 180 group). However, more patients had moderate hypoglycemia (BG, 41 to 70 mg/dL) in the 140 group [27 of 82 (32.9%) vs 10 of 82 (12.2%) in the 180 group; P = 0.003]. Insulin-related hypoglycemia was not associated with the incidence of severe adverse outcomes. Conclusions: Glycemic control of 140 mg/dL safely resulted in a reduced incidence of infection after transplantation compared with 180 mg/dL, but with an increase in moderate hypoglycemia.","PeriodicalId":22632,"journal":{"name":"The Journal of Clinical Endocrinology & Metabolism","volume":"39 1","pages":"451–459"},"PeriodicalIF":0.0,"publicationDate":"2016-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79046813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: This study aimed to investigate whether information on cortical and trabecular bone predict fracture risk independently of aBMD and clinical risk factors. Design and Participants: Cortical area, bone mass, porosity, and trabecular bone volume fraction (BVTV) were measured at the tibia using high-resolution peripheral quantitative computed tomography (HR-pQCT) in 456 men (80.2 ± 3.5 years) recruited from the general population in Gothenburg, Sweden. aBMD was measured using DXA. Incident fractures (71 men) were X-ray verified. Associations were evaluated using Cox regression. Results: Cortical area [hazard ratio (HR) per standard deviation (SD) decrease, 2.05; 95% confidence interval (CI), 1.58 to 2.65], cortical bone mass (HR, 2.07; 95% CI, 1.58 to 2.70), and BVTV (HR, 1.62; 95% CI, 1.26 to 2.07), but not cortical porosity, were independently associated with fracture risk.

Objective: To provide upgraded data on autoimmune comorbidities, replacement therapy, autoantibody profiles, and cardiovascular risk factors. Design, Setting, and Participants: A cross-sectional, population-based study that included 660 AAD patients from the Swedish Addison Registry (2008–2014). When analyzing the cardiovascular risk factors, 3594 individuals from the population-based survey in Northern Sweden, MONICA (monitoring of trends and determinants of cardiovascular disease), served as controls. Main Outcome Measures: The endpoints were the prevalence of autoimmune comorbidities and cardiovascular risk factors. Autoantibodies against 13 autoantigens were determined. Results: The proportion of 21-hydroxylase autoantibody-positive patients was 83%, and 62% of patients had ≥1 associated autoimmune diseases, more frequently coexisting in females (P < 0.0001). AAD patients had a lower body mass index (P < 0.0001) and prevalence of hypertension (P = 0.027) compared with controls. Conventional hydrocortisone tablets were used by 89% of the patients, with a mean dose of 28.1 ± 8.5 mg/d. The mean hydrocortisone equivalent dose normalized to the body surface was 14.8 ± 4.4 mg/m2/d. A greater hydrocortisone equivalent dose was associated with a greater incidence of hypertension (P = 0.046). Conclusions: Careful monitoring of AAD patients is warranted to detect associated autoimmune diseases. Contemporary Swedish AAD patients did not have an increased prevalence of overweight, hypertension, type 2 diabetes mellitus, or hyperlipidemia.

Germline single nucleotide polymorphisms (SNPs) of the vascular endothelial growth factor (VEGF) pathway have demonstrated prognostic value in different tumors. Objectives: Our main objective was to test the prognostic value of germline SNPs of the VEGF pathway in nonadvanced differentiated thyroid cancer (DTC). Secondarily, we sought to correlate analyzed SNPs with microvessel density (MVD). Design: Multicenter, retrospective, observational study. Setting: Four referral centers. Patients: Blood samples were obtained from consecutive DTC patients. Genotyping was performed according to the TaqMan protocol, including 4 VEGF-A (−2578C>A, −460T>C, +405G>C, and +936C>T) and 2 VEGFR-2 (+1192 C>T and +1719 T>A) SNPs. MVD was estimated by means of CD34 staining. Outcome Measures: Rate of recurrent structural disease/disease-free survival (DFS). Difference in MVD between tumors from patients with different genotype. Results: Two hundred four patients with stage I–II DTC (mean follow-up, 73 ± 64 months) and 240 patients with low- to intermediate-risk DTC (mean follow-up, 70 ± 60 months) were enrolled. Two “risk” genotypes were identified by combining VEGF-A SNPs −2578 C>A, −460 T>C, and +405 G>C. The ACG homozygous genotype was protective in both stage I–II (odds ratio [OR], 0.08; 95% confidence interval [CI], 0.01 to 1.43; P = 0.018) and low- to intermediate-risk (OR, 0.14; 95% CI, 0.01 to 1.13; P = 0.035) patients.

There is evidence to suggest ongoing β-cell formation in longstanding type 1 diabetes (T1D), but the source is unknown.\u0000\u0000\u0000Objective\u0000To investigate the PDG compartment of the pancreas in humans with T1D for evidence of an active regenerative signature (presence of progenitor cells and increased proliferation) and, in particular, as a potential source of β-cells.\u0000\u0000\u0000Design, Setting, and Participants\u0000Pancreases from 46 brain dead organ donors (22 with T1D, 24 nondiabetic controls) were investigated for activation (increased proliferation) and markers of pancreatic exocrine and endocrine progenitors.\u0000\u0000\u0000Results\u0000PDG cell replication was increased in T1D (6.3% ± 1.6% vs 0.6% ± 0.1%, P < 0.001, T1D vs nondiabetic), most prominently in association with pancreatic inflammation. There were increased progenitor-like cells in PDGs of T1D, but predominantly with an exocrine fate.\u0000\u0000\u0000Conclusion\u0000The PDG compartment is activated in T1D consistent with a response to ongoing inflammation, and via resulting ductal hyperplasia may contribute to local obstructive pancreatitis and eventual pancreatic atrophy characteristic of T1D. However, there is no evidence of effective endocrine cell formation from PDGs.","PeriodicalId":22632,"journal":{"name":"The Journal of Clinical Endocrinology & Metabolism","volume":"10 1","pages":"200–209"},"PeriodicalIF":0.0,"publicationDate":"2016-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82466418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
